To all whom z't'mag/ concern v Be ,it known that L-JOHN GOOD, a citizen of the'United States, residing inthe borough ofBroo-llyn, county ofKings, city and State of New York, have 'inyented certain new and usefulA improvements-.in Tension-Regulators, of which the following is 'a full and true specification, as required by statute.

-This invention is an improvement intensionl ref g'ulatorsv for long-line spinning or twisting machines and vits object is to improve the construction and inode of operation of such regulators and more especially, to produce an automatic tension controlling device that will exert a variable, fretarding effect on the bobbin, to produce substantially constant tension in the yarn being wound,

thereon, and that will vbe automatically shifted from its position of maximum retarding effect to that of minimum effect, by

the operation of removing a full bobbin from the machine or replacing itwith an empty one, and without attention by the operator. v v

Fig.- Sis a fragmental sectional view along the line III-III of Fig. 2. Fig. 4 is a fragmental sectional view along a continuation of the lineIII--III of Fig. 2. Fig. 5 is a frag-l mental sectional view along the line V-Vof Fig. 2. f

The machine illustrated as an embodiment of my invention includes a flier spindle mounted in the frame l0, and having a The head 15 yis s`plined, on the bobbin spindle '14, yand is capable of beiiigmoved along the spindleby a traversing carriage 16, so as to build the convolutions of yarn on the bobbin in uniform layers. -The spindle 14 is-journa'led' at one end ina bearing v17 provided within the can lierl12, and

at its other end it is supported in a rotaryl sleeve 21 in which itr is suitably splined so that it can be vmoved lengthwise through the Specification of Letters Patent. N

gate yo'r'latch 19 of vany suitable form is mounted 1 on the outer Abearing `18 of the sleeve 21 and Iis preferablyadapted to con` fine the spindle against such lengthwise movement when it is in its operative position engaging the bearing `1'?, although foi" the purposes of this invention any suitable Patented Sept, 1, 1914. y Application filed August 9,1911; Serial No'. 643,075.k ,i

device'm'oved or requiring to be move-d, by

they shifting of the bobbin spindle will be' equally serviceable. Any 'suitable type 'of stop mechanism may be employed with the latch or device 19, which willfprevent the*k machine from being started until the'spindleVA is locked in place, such mechanism being omitted from the' drawings, part of this invention.

`TheV tension or retarding `sleeve y21, journaled in andfbetween the bearings 1S, is

as forming -no provided with a pulley 22 beltedto a fric-y tion pulley 23 looselywmounted upon the power shaft 24. The friction pulley 23 is provided with a radial friction flange to engage the annularcork-faceof a friction disk 25 which is mounted on rthe power shaft and vnormally connected to rotate therewithby its connection with a collar 26 which is setscrewed to the shaft. yThe parts shown iny the drawing vas intervening between the friction disk 25 andcollar 26, by which the two are connected, are parts of a stop-mo 'tion whichis not claimed herein 'and itwill be sufcient for the purposes of the Vpresent case to assume thattlie said disk is keyed ,ory otherwise secured to fthe shaft, as in the case-of the familiar long-line spinner;

The power shaft 24 is belted as'iisual te the flier spindle andalsotothe hauling-off tube in theusual manner and at 'an intermediate pointin its length it is 'provided with af wormi` for. driving the traverse motion and 'the tension regulating device bobbinl spindle, is mountedon ay double s ,100 constituting the special subject of thisinl pitch traverse' screw 49, which is bevel-f-` geared to an inclined counter-shaft'37, the

latter being provided with a' worm-wheel 36, and driven `slowly' bythe worm 35' on the power shaft. lThe carriage 16 is free to g y slide on the screw 49, but is provided with a latch or hook 51 by which it can 'be connected with the nut 50 of the shaft, to be thereby moved back and forth as the screw rotates. Vith this arrangement the bobbin can be manually shifted on the spindle 14 by releasing the latch 51 and sliding the carri-age and head 15 on the shaft as indicated by the dotted lines of Fig. 1. Broken yarn can thus be repaired without releasing and shifting the bobbin spindle, or disturbing the retarding device or the position of the traverse screw 50. y

During the operation of winding the yarn on to a bobbin, the yarn itself, as it leaves the flier revolves the head 15 and consequently the spindle 14, the retarding sleeve 21 and the friction pulley 23. The degree of tension in the yarn is determined by retarding the bobbin spindle which is accomplished by the friction of the pulley 23 upon the friction disk 25, and which for convenience I term herein the retarding device. The diameters of the pulleys 22 and 23 are so proportioned that the latter moves in the same direction at a higher angularvelocity than the disk 25, driven by the shaft 24, so that the friction upon the disk acts as a brake upon the movement ofthe bobbin spindle.

In order that the tension of the yarn passing to the bobbin shall remain constant from the beginning of the winding operation to the end, it is necessary that the braking action on the bobbin be increased as the bobbin fills, because the pull of the yarn leaving the flier then becomes more effective, due to its increasing effective radius of action thereon. This increase is obtained by increasing the friction on the disk 25 at a rate corresponding to the increasing radius of the bobbin, for which purpose a sleeve 27 is looselyy mounted on the power shaft 24 so as to be capable of beine moved longitudinally toward and from the friction pulley23 by means of a lever 28 which is fulcrumed on a vbracket mounted in a convenient position on the frame 10. A coil spring 28 surrounds the shaft 24 between the hub `of the pulley 23` and a collar or enlargement 27 of the sleeve 27, in a position to impart the thrust of the sleeve to the pulley. The lever 28 is actuated by aA slide rod 29 throughy the agency of a coiled spring 30, one end of which is secured to the lever and the other end to a collar 31 whichv is rigidly and also adjustably mounted on the rod. Rack teeth 32 are provided near one end of the rod 29, adapted to engage a -pinion 33 which forms the terminal of a reducing gear-train 34, the said gear-train 34 being driven from the power shaft 24 through any suitable agency, as for example, by the worm 38 of the counter-shaft 37. By these means the rack pinion 33 is slowly driven and in ing force acting on the bobbin.

The springs 28and 30, are one or both set with a normal condition of compression 'and tension respectively, corresponding to the minimum retarding effect ever required for the bobbiinand such effect can be varied in several ways, as for instance, by adjusting the collar 31 on the rack rod, or by adjusting the limits ofthe movement of the latter in obvious manner. The extent of 0peration of the rack-pinion 33 on the rack rod is arranged in accordance with the diameter of the bobbin, being suflicient to increase the retarding eifect thereon proportionately to the growth in the size of the wound yarn upon the bobbin so that the resulting tension on the yarn will at all times be substantially constant. The reducing train of gearing is conveniently formed, as shown in Figs.. 2 and 3, by three parallel shafts 60, 61 and 62 journaled in the frame piece 63 which supports the counter-shaft 37. The slowest of these shafts (62) carries the rack pinion 33, while the one at the other end, marked 60, forms the support for one of the ends of the rack rod 29. For this purpose a small bracket 45 is pivotally mounted on, or concentric to, the shaft 60 embracing the rackrod, and in which the latter is free to slide as moved by the pinion. Preferably a spline screw 46 is threaded into the bracket to engage a spline groove in the rack'rod to prevent -its rotation as indicated in Fig. 5, but it will be understood that any suitable `means of sliding support may be provided for the rack rod instead of that shown. The opposite end portion of the rack rod 29 yis carried in a sleeve- 43 pivotally hinged on a stud 44 projecting from the side of a` lever 39. The end of the sleeve is provided with a cushion washer 42, adapted to be engaged by an adjustable stop collar 41 setscrewed onto the rack rod to limit its sliding-movement. The lever 39 is fulcrumed at 40 to the frame piece 63 and is connected in any suitable way, as for instance by the link 64, with the bobbin spindle-latch 19 above referred to, so thatthe operation of the latterin one directionor the other, willy effect the disengagement of the rack-pinion 33 from the rack teeth of the rod, as for instance by lifting sleeve 43 and thereby swinging the rack rod about the shaft 60- as anl axis, far enough to lift its rack-teeth out of mesh with the teeth of the rack-pinion 33. Vhen suchdisengagement has taken place, the tension of the springs 28 or 30,

or both, will 'serve to draw the rod through I. placing the rod in its initial positioncorresponding to minimumk retarding efect. By reason of the fact that the fiier is of the open-end type as shown, and also that the traverse carriage is readily disconnected from the traverse nut, as above explained, itv` will be observed that the latch-device 19 isl operated only when a bobbin is removed from the machine, so that the gradual increase in the retarding effect will 4thus ktake place without interruption, continuing for as long as the same bobbin remains in the machine and untill it is full or removed. The succeeding empty bobbin will in every case encounter the minimum retarding eifect which thereupon increases in likey manner, thereby insuring constant tension in the yarn. I

So far as my invention is concerned with the relation abovek described between the bobbin and the tension controlling meLIlS it will be further observed that the particular construction and mode of operation of thelatter is not of consequence, provided thesame 1s capable of applying progressive retarding eect and of instantly relievingthe same or restoring it to the minimum, by the movement or operation of the agencies by which the bobbin is removed from the bobbin spindle. The invention, however, also includes the specic construction of the means for increasing the retarding eect and the other features and combinations of features pointed out in the following claims.

rI he invention further includes the application of an automatic power knock-off device to the type of tension controlling mechanism above described. Such means, in the present embodiment, comprises a collar adjustably fastened to the rack rod 39 and appropriately formed to have engagement with a bell-crank 71, which is a part of the regular stop motion mechanism. Then such engagement takes place the bell-crank is lifted from a notch in the belt shipper bar 72, which is thereupon free to move under the influence of its spring 73 to shift the belt from the fast to the loose pulley, or otherwise to turn off the power.
